frame

Hi everyone, I am a first time poster and am really glad to have found this site! I rode a lot from 75-86, but a couple of very close calls over a three week period involving 4 wheeled idiots running stoplights and just missing me convinced me to stop. Now that I have an 18 year old son who...

Hello everyone, I recently bought a 1978 CB750 K7, which has dual front brake disks and rear brake disk. I want to change the stock comstar wheels for stainless steel spokes wheels but I'm having some issues in finding the right hubs for the conversion. I have seen a lot of different hubs from...

Is there any trick to removing the rear wheel bearings (at least one is bad) from my K3? Do I just knock them out from the opposite side with a hammer and punch?

Got my 76 cb750 out of storage and the rear tire is not holding air. Using soap/water I found the leak at the base of the tire valve stem. I would like to replace this the cheapest way possible. Any tips/advice? My repair manual is not very helpful. I'm having trouble finding the correct valve...

I need this part - 007 PIPE (LOWER) 51430-392-003 NOT AVAILABLE Cannot find it anywhere, any help? Anyone have one I can purchase?

I'm getting around to fixing up a K3 that someone gave me (yes, gave me) last summer, and while I was washing it today, I noticed that the swingarm has some side-to-side play in it. I've owned 30+ Japanese bikes over the past 46 years, but I've never noticed slop in a swingarm before. Is some...

Hi all - looking for recommendations on a good travel fairing; I'd like to do a few highway trips and with no fairing / wind deflector at all I get thrown around a good bit. Definitely looking for something a bit more minimal - I don't mind some discomfort.

I'm working on re-habbing a '71 CB750. The bike currently does not have a tach and the speedo looks a little dicey. Are tachs and speedos interchangeable at all between model years? Since it may take me a while to find / afford 1971 tach & speedo, can I use ones from later years at all?

Dear Forum: Thanks to some forum members and You Tube, I have opened the speedometer housing from my '71 K1 to replace the Speedo face. The inside of my speedometer housing has all sorts of rust and dry dirt. As soon as I loosen the set screw to the trip meter, I will pull the speedometer...

I have a 1978 cb750k i am trying to work out a tail light issue the brake light works fine but no running light i have a wiring diagram. my question is if the brown wire is for the tail light/running light. and according to the diagram it goes to the combination switch. where is this switch...

Hey everyone. I recently obtained an 81 CB750C. I'm having some speedometer issues. From doing some research I've found that these old bikes are usually off by about 10 or so mph. However mine was layed down by the PO. When I check my speedometer against a GPS it starts off 5mph low and then...

I've been looking around (again) for ammo cans to mount as saddle bags. I'm thinking about using the "fat" .50 cal cans and was wondering if anyone knew a decent way to mount them. At first I thought, "drill some holes and just throw them on there" but quickly realized that would be bad. So...

Gentlemen, any advice for center stand removal would be much appreciated. In particular the spring. Is there a trick to removal other than brute force? thanks

Hi. I'm new to this forum and have a question, so maybe someone can advise. I have a 1978 CB750K and the tank is getting a bit aged. I've cleaned it, soldered up some pin holes and coated it but am thinking it's time for a replacement. Could someone please let me know which model years have...

I'd like my wife to ride along with me but she doesn't feel comfortable without something at her back and preferably something to hold onto besides me. My grandpa had a huge sissy bar (seriously, this thing is about 3 feet tall) but because it isn't 1970 now, I will not ride with it. Where...

hello my name is chris.this is my situation I have a 1980 750 that has no issues but has no title. I can get a 82 750 nighthawk frame I just need to know if I can swap it all over to it or do I need to get a different frame. help! what frames will for it. thank you.

So I've been around motorcycles most of my life, but I've never owned one. Now I'm getting a little more serious about actually doing it. I should note, I dont want to just buy a bike, hop on it, and go, I want a hobby, a toy. Ive always liked the CB750, and have been wanting to do a cafe bike...

OK, this is a rather silly problem but maybe someone has a solution. I'm a small short guy, I couldn't place both feet on the ground in the saddle with stock height, plus I like lower bikes. So I passed the forks through the triple tree by 2" and got 11" shocks for the rear. Now I can ride like...

I'm currently restoring a CB750KZ - frame is bare and powder coated and the engine is almost ready to go back in after a complete strip down. Has anyone any experience on the best way to get the engine back in? Previous restores i've jacked the engine into the frame but i'm seeing people who...

Hi everyone, I bought a 1977 CB750 a couple of years ago which turned out to be a complete basket case of a cafe project. Wine + Ebay = poor decision making. Should be common sense but I had to learn the hard way. The list of problems is far too long to list here but suffice it to say I'm...

I am looking at buying another CB750. Do all of the SOHC bikes have the same frame? I found a good deal on a 1978 but don't like the tank and seat. What would it take to make 1978 look like a 1975 as far as the tank, seat and side covers? I like the older tanks and would probably put a cafe...

General question - I have lowered my Super Sport 2" in the back and plan to drop the front about an inch. The center stand will be removed. What are my options for the kick stand? Heat it up and bend it? Cut and weld? If I heat it should it be quenched or air cooled? Thanks.

Hey everyone, Any suggestions on where to get replacement side covers? (for both oil tank and electrical) Cheers!

Let me describe the bike and situation. Bike is a '76 K6 with 7,000 miles and stored poorly were some rust accumulated from sitting (1988-2012). On the right side there is some damage; front directional bent and scraped, headlight bracket pushed in, tachometer housing dented and scraped...

Hi all. I recently purchased some really nice Hondaline hard saddlebags with the side brackets but there is a missing piece that connects to the back. Not sure if its a backrest or luggage rack or combo of the two. I posted some pics. Does anyone know what slides on there and have a pick of it...

I hear that is a common complaint that it is hard to get a CB750K up on the center stand. I'm on the short/light side and I certainly have that problem. Solution is to park the bike on a 2x10 and then the rear wheel is already raised enough that I can raise it easily onto the stand. Does...

I want to remove my gas tank on my 82 cb750k but it has about 4 gallons in it. Do I need to drain the tank before I remove it or can I just turn the gas flow to off and remove tank with gas in it?

Hi, I'm new to the forums, but I have been coming here for info as I have been repainting my bike. It is the first bike I have owned and tore down to the frame. I have it all back together now. After getting it running and going for a test drive I have noticed it pulling to the right. When you...

looking at pics online i see alot of people running a new frame from near the rear tank mount location down to existing swing arm, is this a safe way to build a frame? i know you can buy the weld on tail on ebay for about 3 bills, but i am on a very tight budget and thinking this might be a...

Hi All, I need a new frame for my cb750 1978 I just found a 1981 cb750 but I wonder if the frame is the same ??? And if not what year should I focus on, thanks in advance, Eric
